    摘要: Inorganic and organic compounds containing fluorine can be produced, for example, from corresponding chlorine-containing compounds by chlorine/fluorine exchange using fluorinating agents. Monocyclic or bicyclic compounds containing at least two nitrogen atoms, at least one of which is incorporated into the ring system, can be used as catalysts or fluorinating agents for chlorine/fluorine exchange reactions to produce sulfurylchlorofluoride, sulfurylfluoride or a carboxylic acid fluoride. It is likewise possible to carry out HF addition to unsaturated carbon-carbon bonds or chlorine/fluorine exchange at carbon atoms. For example, monochloro or dichloro malonic acid esters can be converted to difluoro malonic acid esters. Work-up of the reaction mixture can be simplified by using suitable solvents which force the reaction mixture to exist in two phases.

    摘要: A nitrous acid salt is added at a temperature of 10 to 80null C. to an aqueous solution which contains an optically active 2-aminocarboxylic acid (4) and a protonic acid, the amount of the latter acid being 1 to 3 equivalents to the former, and which has a proton concentration of 0.5 to 2 mol/kg to conduct a reaction to thereby produce an optically active 2-hydroxycarboxylic acid (1). Thionyl chloride and a basic compound are caused to act on the compound (1) to chlorinate it and simultaneously invert the configuration in the 2-position. Thus, an optically active 2-chlorocarboxylic acid chloride (5) is induced. The compound (5) is hydrolyzed to induce an optically active 2-chlorocarboxylic acid (2). The compound (2) is reacted with a thioacetic acid salt to incorporate an acetylthio group thereinto and simultaneously invert the configuration in the 2-position to thereby produce an optically active 2-acetylthiocarboxylic acid (3). 1
